Genes affected
RPS17 (HGNC:10397): (ribosomal protein S17) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of four RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 40S subunit. The protein belongs to the S17E family of ribosomal proteins and is located in the cytoplasm. Mutations in this gene cause Diamond-Blackfan anemia 4. Alternative splicing of this gene results in multiple transcript variants. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Apr 2014]

Diamond-Blackfan anemia 4 Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Pediatric Oncology and Hematology Unit, National and Kapodistrian University of Athens | Dec 16, 2022 | The c.156-1G>A variant in RPS17(NM_001021.6) has been found in a girl with Diamond-Blackfan anemia phenotype and was absent from large population studies. Additionally, family segregation analysis showed that the variant is de novo. The variant is expected to disrupt normal splicing. In summary, this variant meets our criteria to be classified as likely pathogenic, based on the segregation study, absence from controls, and possible aberrant splicing. - |
